Valmet DNA Automation technology to the world’s largest data center excess heat recovery project in Finland

Valmet will supply its Valmet DNA Automation technology to the data center heat recovery concept developed by Fortum and Microsoft. The project is one of a kind: there is no data center heat recovery concept of a similar scale anywhere else in the world. Valmet DNA will control water-to-water heat pumps, air-to-water heat pumps and two electric boilers at two Fortum Power and Heat Oy’s heat pump plants which will be built in Espoo and Kirkkonummi, Finland.

The order was included in Valmet’s orders received for the first quarter of 2024. The value of the order is not disclosed. The delivery to Kirkkonummi will be taken over by the customer in September 2025 and the delivery to Espoo in December 2025.

The heat pump plants will recycle emission-free excess heat from Microsoft’s two planned large data center areas to Fortum’s existing district heating network. The data centers will eventually provide 40% of the consumed heat in the network area. Fortum’s district heat in Finland will be produced coal-free during 2024 and carbon-neutrally before 2030.

”The excess heat offtake project from Microsoft’s data center areas is our flagship project in decarbonizing our district heat production. We wanted to ensure that the automation technology partner is reliable and has the exact solutions we need. Valmet has a convincing track record in our other production sites, which made our choice quite straightforward”, says Teemu Nieminen, Director Project Execution at Fortum’s Heating and cooling business in Finland.

“We are excited to be involved in turning Fortum’s district heat production carbon neutral in Finland. The heat pump plants are part of Fortum’s district heating system, including the Suomenoja power plant in Espoo that has been running with Valmet’s automation for years. In the future, the new plants can be controlled and monitored remotely from the Suomenoja power plant. We have earlier supplied similar Valmet DNA Automation Systems to Fortum’s Vermo 2 and Mankkaa heat pump plants,” says Tom Bäckman, Sales Manager, Automation Systems, Valmet.
